Comprehensive Q&A covering QSC GLP1 products, shipping to Europe, compound pharmacology, purity standards, and ordering from QSC Peptides.
QSC GLP1 (qscglp1.com) is the dedicated research reference and purchasing guide for QSC Peptides GLP-1 receptor agonist compounds — Semaglutide, Tirzepatide, Retatrutide (LY3437943), and Cagrilintide/CagriSema blends.
QSC Peptides stocks: Semaglutide (10mg, 15mg vials), Tirzepatide (15mg, 20mg, 30mg vials), Retatrutide/LY3437943 (5mg–60mg vials), and Cagrilintide+Semaglutide CagriSema blend (10mg vials). All ≥99% purity with COA.
Retatrutide (LY3437943) is Eli Lilly's triple GLP-1R/GIPR/GCGR agonist. Phase 2 clinical research (NEJM 2023) showed approximately 24–26% average body weight reduction at 48 weeks — the highest reported for any GLP-1 class compound. QSC Peptides offers 5mg to 60mg vials.
CagriSema is a pre-blended combination of Cagrilintide (long-acting amylin analog, AMYR1/3 agonist) and Semaglutide (GLP-1R agonist). Phase 2/3 data shows ~22–25% weight reduction. QSC Peptides offers 10mg (5mg+5mg) vials.
All QSC Peptides GLP-1 compounds are ≥99% purity verified by third-party analysis, with Certificate of Analysis (COA) provided on every order.
GLP-1 is an incretin hormone secreted by intestinal L-cells in response to nutrients. It binds GLP-1R — a class B GPCR — to drive glucose-dependent insulin secretion, appetite suppression via hypothalamic circuits, gastric emptying delay, and β-cell preservation. Native GLP-1 has a ~2-minute plasma half-life; synthetic analogs extend this to days via albumin binding.
Semaglutide is a GLP-1R monoagonist. Tirzepatide is a dual GIP+GLP-1R co-agonist (twincretin), adding GIPR activation which provides insulin sensitization via adipocyte fat oxidation and synergistic GLP-1R amplification — driving ~5–7% greater weight reduction than semaglutide alone.
GCGR (glucagon receptor) agonism in Retatrutide adds energy expenditure increase via UCP1-mediated brown adipose thermogenesis, hepatic fat oxidation (NAFLD research), and direct lipolysis — effects that GLP-1R and GIPR agonism cannot replicate, explaining Retatrutide's superior ~24–26% weight reduction.
Jastreboff AM et al., New England Journal of Medicine, 2023 — Phase 2 randomized controlled trial of Retatrutide (LY3437943) in obesity. The 12mg arm showed ~24% average weight reduction at 48 weeks, with approximately 100% of participants achieving ≥5% weight loss and ~83% achieving ≥15%.
Ozempic and Wegovy are brand names for semaglutide manufactured by Novo Nordisk for therapeutic use. QSC Peptides Semaglutide is research-grade semaglutide for in vitro research purposes only — not for human consumption or therapeutic use.
Mounjaro and Zepbound are brand names for tirzepatide by Eli Lilly for therapeutic use. QSC Peptides Tirzepatide is research-grade for in vitro research purposes only.
Semaglutide has approximately a 7-day plasma half-life via C18 fatty acid-mediated albumin binding. This makes it suitable for once-weekly research protocols requiring stable GLP-1R activation.
No. All QSC Peptides products are strictly for in vitro research purposes only. Not for human consumption, therapeutic, veterinary, or diagnostic use. Not for sale to individuals under 18.
